JOSEPH W. HUGHES, OF NEWBURYPOBT, MASSACHUSETTS.

IMPROVEMENT IN BlLGE-WATER VALVES FOR SHIPS.

Specification forming part of Letters Patent No. 166,526, dated August10, 1875; application filed May 28, 1815.

To all whom it may concern Be it known that I, JOSEPH W. HUGHES, ofNewburyport, in the county of Essex and State of Massachusetts, haveinvented a new and Improved Stop-Water for Ships Bilges, of which thefollowing is a specification:

The invention willfirst be described in connection with drawing, andthen pointed out in the claim.

Figure l is a transverse section of a ship having my improved stop-waterand the fore and aft passages in the floor-planks, the section beingtaken on the line a: m of Fig. 2; and Fig. 2 is a plan view.

Similar letters of reference indicate correspondin g parts.

A represents the transverse ribs or timbers, to which the outsideplanking B and the inside floor-planking O are attached, and betweenwhich the bilge-water lies. D repre- Without these stops the water flowsback away from the pump, which is of necessity arranged in the center,so that it sucks air only until the water comes back, thus losing muchtime, which in some cases of danger is of vital importance, and it alsowastes power. F represents grooves in the under side of thefloor-plankin g 0, which I propose to make in addition to the grooves G,commonly used in the outside planking below the timbers, to make certainof having free passage for the Water fore and aft, which the passagesbelow do not afi'ord, because they clog with sand and other matterscollecting and remaining in them by gravity, but which cannot remain inthe upper passages.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of a self-closing stop-valve, F, withthe ribs A and planking B O of a ship, to retain the bilge-water in themiddle of the ship, substantially as specified.
